High energy nucleus-nucleus collision experiments expedit on the QCD phase diagram toward the deconfined partonic phase. PHENIX experiment at RHIC has found a thermal compoment in the direct photon spectrum, suggesting a temperature above the predicted phase boundary at around 170 MeV. The ALICE experiment at LHC started a further scientific expedition in 2009. First physics results and latest analysis status from p+p collisions at √ s = 900 GeV, 2.36 TeV and 7 TeV are reported, along with the plans and prospects at ALICE/LHC. The first Pb+Pb running at √ sNN = 2.75 TeV is scheduled to begin in November, 2010, with expectations for exciting physics harvests toward global and comprehensive understanding of properties of the deconfined partonic matter, especially via penetrating photon and lepton measurements.
